No, that 3200 is about half as fast honestly. O.k well maybe not that bad but a 6800GT should be faster than your 3200 IGP. Even so, you might get it to run on the lowest settings. If your happy with it or not is another story ^_^
First lesson in buying a laptop, get a bit over what you think you want to pay for it, because they are not upgradable easily. Paying $500 on a laptop that will not run what you want is a huge waste compared to paying $700 for one that will actually be useful. 3200 is no-where near the 9800GT.
